  3. Anatomy of antihelix

  4. antihelical shelf (= conchal shelf)

  5. absent antihelix

  6. additional crus of antihelix(= Stahl ear)

  7. angulated antihelix

  8. variable width of inferior crus of antihelix(a=narrow, b=average, c=broad)

  9. Underdevelopped (a), average (b) & prominent (c) inferior crus of antihelix

  10. variabel protrusion of antihelix stem(a=marked underdevelopment, b=mild underdevelopment, c=average, d=mild prominence, e=marked prominence)

  11. serpiginous stem

  12. superior crus of antihelix(a=absent, b=slightly indistinct, c=average, d=slightly more distinct, e=very distinct, sharp)
